ActionError

Description

A domain error returned from an action as Err(ActionError). Serialized into the { "error": ... } envelope (HTTP 422) and surfaced on the client as a thrown OssidoActionError. Distinct from a panic, which is caught and routed through the framework's ServerError overlay.

Signature

pub struct ActionError {
    pub message: String,
    /// Optional per-field validation messages (e.g. `{ "email": "required" }`).
    #[serde(skip_serializing_if = "Option::is_none")]
    pub fields: Option<HashMap<String, String>>,
}

Examples

return Err(ActionError::message("Please enter a valid email"));
// or with per-field messages:
return Err(ActionError::with_fields("Validation failed", fields));
